Article doesn't mention SILLIAC, a similar computer at Sydney University.
> Like most of the IAS family, SILLIAC was not an exact copy of ILLIAC. One important change was the use of 2C51[6] valves in place of the more common 6J6.[7] The 2C51 had been developed by Bell Labs for use in undersea telephone repeaters and had about 5 times the life (for 6 times the cost). This decision significantly improved the reliability of SILLIAC compared to its contemporaries.

Includes Barry de Ferranti, a distant cousin of people of English engineering and computing fame. https://www.abc.net.au/radionational/programs/scienceshow/silliac---australias-first-supercomputer-built-50/3384532 https://www.abc.net.au/radionational/programs/scienceshow/si...
- pinewurst 6y agoNo, SILLIAC is related to the original tube-based ILLIAC I, which is absolutely nothing like ILLIAC IV other than in name.
